POW: full name of proof of work

pos: proof of stake

both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency

the difference is:

1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power

POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

2. Lightning bitcoin has not been well known because it is a bifurcated coin of bitcoin. Many users in the coin circle instinctively dislike this kind of token. Fork coin has now become synonymous with money and running. But what you may not know is that all bifurcated bitcoin can be called currency in the eyes of foreign regulators. The US SEC only recognizes bitcoin and Ethereum as currencies because they have not concted ICO in public channels. Accordingly, these bifurcated currencies are regarded as currency. And lightning bitcoin is the only one that doesn't pre dig in the fork coin. You can imagine that bitcoin is 100 banknotes issued by a bank, and all kinds of bifurcated banknotes are equivalent to banknotes of different denominations issued by the bank. You may not be able to understand the valuable value of this. When it comes to the circulation of entities, if you are a bifurcated coin of bitcoin, it is easy to pass the government compliance. In short, the reason why the Grand Prince BCH can get through the physical circulation in Japan so quickly is just the light of bitcoin
then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders

so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.

3. virtual currency, or more formally, digital currency. Although it carries the words of currency, it should be a kind of digital financial asset. Its value comes from the application of blockchain technology in payment, clearing, notarization, digital verification and other aspects, which brings efficiency improvement and cost rection
as you can understand it, it's like the stock of these technology service providers. As these technologies become more and more widely used, these virtual coins will become more and more valuable
bitcoin, which appeared in 2009, is the first kind of virtual currency in the world. It is also the first time that it has applied the blockchain technology which is popular all over the world
after bitcoin, there are many imitators in the market. They either improved on the basis of bitcoin, or put forward more grand technical ideas than bitcoin. Virtual currency, which is common in other markets and considered as "regular army" by instry insiders, is collectively referred to as competitive currency. Together with bitcoin, it forms the whole digital currency market, with a total market value of nearly 100 billion US dollars
there are thousands of virtual currencies in the market, most of which are risky; In addition, there are many MLM coins that are simply for the purpose of deceiving people< In order to help you avoid being cheated, the following is a brief introction to the main "regular army":
1. Bitcoin (BTC)
bitcoin is the first virtual currency in the world, with a total of 21 million. At present, more than 16 million bitcoins have been "g up", with a total market value of about US $45 billion, equivalent to half of the total market value of all virtual coins. It is well deserved to be the number one in the coin circle
bitcoin has been accepted as payment currency by hundreds of thousands of businesses around the world; In addition, bitcoin has also become a common money raising currency in various blockchain technology startups. Therefore, with the increasing demand for bitcoin, the value of bitcoin is likely to grow in the long run
2. Eth is regarded as "bitcoin version 2.0" and is the most likely competitor to surpass the market value of bitcoin. Some time ago, the market value of bitcoin was close to that of bitcoin. However, e to the price rection in the recent month, the market value of bitcoin is only about half of that of bitcoin
Ethernet coin was born in the summer of 2014. It is issued on the Ethereum blockchain, which is different from bitcoin. Ethereum blockchain is a decentralized application platform, which solves the problems of bitcoin's technical limitation in currency application and insufficient function expansion, so it has great technical advantages
3. Bitcash (BCH)
BCH inherits a small part of bitcoin's legacy, the name of bitcoin's cash is also good, and the image logo also inherits a part of bitcoin. The ecology of BCH is also good
BCH pursues to be a world currency and an underlying platform for chain application. BCH is actively deploying the main chain expansion and developing the two-tier network to realize the ideal
the whole ecology should be made efforts from two aspects. The first direction is the expansion of the main chain, payment experience and function improvement. Capacity expansion is the guarantee to keep the certainty of monetary transaction fees very low. Improving the payment experience, including popularizing zero confirmation, pre consensus, and possibly shortening block time, are all evolving towards a better payment experience. The main chain function is perfect, including Op_ Return expansion, token issuance, new opcode addition
with the expansion of BCH main chain function, BCH based applications can be developed. The most famous are the decentralized microblog like memo, the paid download seed application like joystream, and the decentralized encrypted communication like Keyport
the second direction is to develop layer-2 network. Build a new blockchain based on BCH network, such as wormhole and kenoken, which are similar to Ethereum network based on BCH. BCH undertakes more complex block chain functions, such as notification contract, through two-layer network. The competition direction of BCH layer 2 network is to compete with the side chain of BTC
4. Lightning bitcoin (LBTC)
bitcoin has been developing for 10 years. In this decade, bitcoin has experienced three important splits, and now it has become four kinds of currencies. The first is BTC, which has inherited most of bitcoin's heritage; The second is BCH; The third is BSV and the fourth is LBTC
LBTC was born to break the power monopoly of big miner and bitcoin core bitcoin, introce more new features and functions for bitcoin, and greatly improve its performance. Lightning bitcoin (LBTC) is a peer-to-peer e-cash system, which is an innovative experiment based on bitcoin. It uses the dpos consensus mechanism based on utxo to separate the voting right and accounting right, so that the token will not be kidnapped by any party. It is a global value Internet transmission protocol with high speed, low handling charge and high scalability. Due to the adoption of dpos consensus mechanism, users can participate without professional mining machines, achieving real decentralization
the above four are the most mainstream bifurcated versions of bitcoin protocol. They are also investment procts that can realize your desire of soaring wealth. Senior managers can play with them, but the premise is that you need to be prepared for huge losses - because they are very volatile
for Xiao, I would like to say: Although virtual currency is a secret weapon for ordinary people to counter attack the sudden wealth, it's very difficult for you to make a lot of money from it
in addition, at present, the price of virtual bitcoin is at a high level, and it can not be ruled out that it will mainly be sideways in 2019. At this time, I think it is a good choice to some other mainstream bifurcation currencies, such as BCH, BSV and LBTC.

4. No,
BTC is the official abbreviation of bitcoin,
NMC media chain coin is based on three decentralized blockchain use landing projects, namely, coin call [blockchain information community portal], coin check [blockchain network query], ncoin [digital currency exchange], and three decentralized use channels form an open, shared, and autonomous ecosystem, In the three channels, NMC is used for circulation, with a total amount of 600 million issued and no additional ones will be issued. At the same time, the distributed domain name system based on bitcoin technology has the characteristics of security and non censorship. There are no cheaters. However, e to the relative lack of supervision, digital currency is easy to be pulled up or sold, so it may become rich overnight, or it may lose all the principal overnight. This is the general nature of digital currency, not just NMC currency.

5. There are four questions you need to think about the project you're working on
1: what is the basis for issuing currency or points
2: what is the basis of circulation
3: what is the basis for its value-added
4: how do companies make money?
